Knitting fabric is one of preferred fabrics by many customers due to proper shape fitting, softness, flexibility, elasticity and good elastic recovery. Knitting is very well-known fabric manufacturing method in which intermeshing or inter-looping of yarn loops is the principle adopted to produce textile structures. Knitting is formed by a series of loops, intermeshing in rows and each hanging from the last. For this study, flat knitting system was selected for manufacturing the fabric samples. Here, Yarn count, Stitch length, Fabric Design were the three factors, along with this, air permeability and bursting strength were the two responses on which the effects were observed. For statistical analysis of effect of stitch length on knitted fabric quality, Box-Behnken design was has applied. The experiment was carried out with three levels and variables using Box-Behnken design combined with response surface methodology [RSMJ. Yarn count, Stitch length, Fabric Design were independent variables selected to get desired yarn strength as well as breaking elongation. Data were fitted to a Cubical model; model fitness was evaluated by the analysis of variance, which indicates P < 0.0005. Individual and interactive effects of the independent variables on abrasion resistance by checking average loss in weight and thickness were interpreted using the proposed mathematical model.
